Carl Du Prel

Karl Ludwig August Friedrich Maximilian Alfred, Freiherr von Prel, or, in French, Carl Ludwig August Friedrich Maximilian Alfred, Baron du Prel (3 April 1839 Landshut, Germany – 4 August 1899 Heiligkreuz, Austria), was a German philosopher and writer on mysticism and the occult. In the literature it has become customary to refer to him under various abbreviated French forms of his name, usually "Carl Du Prel", "Baron Carl Du Prel" or simply "Baron Du Prel".

Biography

He was born at Landshut. After studying at the Ludwig-Maximilians-Universität München he served in the Bavarian army from 1859 to 1872, when he retired with the rank of captain. He then gave himself up to philosophical work, especially in connection with the phenomena of hypnotism and occultism from the modern psychological standpoint. In 1868 he received the degree of doctor from the University of Tübingen in recognition of a treatise on the psychology of dreams (Oneirokritikon. Der Traum vom Standpunkt des transcendentalen Idealismus). Following this achievement, he became something of a protege to Eduard von Hartmann, promoting and vigorously defending his work Philosophy of the Unconscious (1869).

Du Prel sought to combine early parapsychological research and Kantian transcendental idealism to argue that mystical experiences were universal and subjective, paralleling a similar argument made by William James. He attempted to deduce the existence of spirit, apart from, and yet entering from time to time into connection with, the phenomena of the senses, by an examination of the relation between the ego of thought and the age of sensible experience as understood by Immanuel Kant.
